How do I choose the right Garage Door?


Choosing the right garage door involves several important considerations. Let’s break it down:

  1. Purpose and Usage:
    • First, think about how you plan to use your garage. Is it primarily for parking your car, a workshop, storage, or perhaps even a games room?
    • If it’s a workshop, consider adding windows for natural light and insulation to dampen noise from power tools.
    • For a games room, focus on insulation and possibly a heavier gauge steel door.
  2. Style and Aesthetics:
    • Your garage door significantly impacts your home’s curb appeal. Choose a style that complements your house.
    • If you live in a weatherboard bungalow, opt for a garage door with characteristics similar to weatherboards (e.g., Fineline or Ribline Colorsteel).
    • For modern homes, go for simple designs (like SMOOTH PANEL steel or aluminum) that enhance the streamlined architecture.
  3. Material Selection:
    • Consider the material that best suits your needs:
      • Steel: Durable, long-lasting, and available in various gauges. Steel doors are popular due to their value and performance.
      • Aluminum: Lightweight and resistant to corrosion. Ideal for coastal areas but requires regular washing.
      • Wood: Natural and charming, but it demands regular maintenance.
      • Insulation: Insulated doors provide better temperature control and noise reduction.
